In this paper we report on p‐type arsenic doping of CdTe and HgTe/CdTe superlattices by photoassisted and conventional molecular‐beam epitaxy (MBE). We also report on some of the problems involved in doping and growing the HgTe/CdTe superlattice

Low background applications place the most stringent requirements on detector material, requiring the lowest possible dark currents, highest quantum efficiencies, negligible image persistence (image latency or “ghosts”), high operability, and goo

Epitaxial YBa2Cu3O7−x(YBCO) films were grown on SrTiO3‐buffered (100) MgO substrates by pulsed laser deposition. The SrTiO3 layer of about 500 A thick serves a dual purpose to provide a better lattice match to the YBCO films as well as a diffusio
